I love all the people complaining about stealing electricity. While the idea of unsecured rigs and moving them around is the real actual issue, people seem so conditioned to just reply "stealing electricity!!!!!! you are a bad bad man" Chill out, a 6 card rig uses like $2-4/day. In hotels, you're going to stay only a few nights. Big deal....
Why don't you just call up a hotel, explain what you want to do, and ask for permission? If it violates a fair use of utilities clause, it is stealing. Theft is theft. Doesn't matter if it's a candy bar or a truck load of flat screen tv's. The dollar amount isn't what I have a problem with. The moral compass of the person who is willing to do it without permission is what I have the problem with. Slippery slope people.
